o-Phenylenediamine (OPD) (CAS: 95-54-5) is the simplest aromatic diamine. There are three isomers, namely o-Phenylenediamine, m-Phenylenediamine and p-Phenylenediamine. o-Phenylenediamine's color is easy to change upon exposure to air, from white to yellow, brown, purple, and finally into black.
o-phenylenediamine has active chemical properties, being able to have condensation reaction with acid, aldehydes, ketones and other compounds, generating heterocyclic compounds; it can also have oxidation, condensation, substitution and diazotization reaction.
Phenylenediamine is used as a fluorescent indicator and chromatographic analysis reagent. It is used for the identification of copper, gold, iron, magnesium, vanadium, ammonia, hydrogen sulfide, sulfur dioxide and chromic oxide, etc., and manufacturing azo dyes, fur dyeing and photographic materials. , Printing and dyeing industry.
1. It can be used as a cationic dye intermediates, being the main raw material of pesticides, carbendazim and other fungicides.
2. It can be used as analytical reagent, fluorescent indicator, also used in organic and dye synthesis. It can be used as an important intermediate in the manufacture of other fine chemicals, pesticides, pharmaceuticals and dyes, pigments, and fungicides, vulcanization accelerators for rubber, developers for the photographic industry, fur dyes and hair dyes. It is also used in hair dye formulation, as a photographic developing agent, and in organic synthesis.
3. Phenylenediamine is the intermediate of fungicide carbendazim, methyl thiophanate, and thiabendazole, but also insecticides quinalphos intermediates.
o-Phenylenediamine has moderate toxicity, often due to inhalation of dust or skin absorption caused by poisoning (the latter phenomenon mostly). Inhalation of dust can cause rhinitis, bronchitis, frequent fever, causing unique asthma and vagal nervous tension caused by the tracheal inflammation, can cause severe acute eczema and eczema. m-Phenylenediamine can cause methemoglobin changes, while the p-phenylenediamine can cause bronchial asthma, allergic dermatitis.
